英文:
Arabic text is revering lines in reportlab
问题
formatted_paragraph = Paragraph(bidirectional_text, paragraph_style)
return formatted_paragraph
arabic_text = ''وحدة1 وحدة2''
Here's the output:
وحدة2
وحدة1
Here's what I expected:
وحدة1
وحدة2
英文:
In reportLab, I need to display an arabic paragraph. I am using arabic-resharper and bidi-algorithm. The problem appears in the algorithm that reverses lines.
My code is:
def format_arabic_paragraph(arabic_text: str, paragraph_style: ParagraphStyle):reshaped_text = arabic_reshaper.reshape(arabic_text)bidirectional_text = algorithm.get_display(reshaped_text)formatted_paragraph = Paragraph(bidirectional_text, paragraph_style)return formatted_paragrapharabic_text='وحدة1 وحدة2'
Here's the output:<br>
وحدة2<br>
وحدة1
Here's what I expected:<br>
وحدة1<br>
وحدة2

Reportlab支持部分双向文本（Bidirectional）功能，使用Fribidi进行支持。默认情况下禁用。在reportlab/rl_settings中有一个名为rtlSupport的选项。请参阅用户指南中的站点配置部分。在我的安装中，我添加了一个名为~/.reportlab_settings的文件，并添加了一行rtlSupport=1。
在ParagraphStyle()中设置wordWrap="RTL"。
示例：
from reportlab.platypus import Paragraphfrom reportlab.lib.enums import TA_RIGHTfrom reportlab.pdfbase import pdfmetricsfrom reportlab.pdfbase.ttfonts import TTFontfrom reportlab.lib.pagesizes import LETTERfrom reportlab.lib.styles import ParagraphStyle, getSampleStyleSheetfrom reportlab.platypus.doctemplate import SimpleDocTemplatepdfmetrics.registerFont(TTFont("Arial Unicode", "Arial Unicode.ttf"))arabic_text='وحدة1 وحدة2'doc = SimpleDocTemplate("repro_ar.pdf",pagesize=LETTER,rightMargin=280,leftMargin=280,topMargin=72,bottomMargin=72,)styles = getSampleStyleSheet()normal_arabic = ParagraphStyle(parent=styles["Normal"],name="NormalArabic",wordWrap="RTL",alignment=TA_RIGHT,fontName="Arial Unicode",fontSize=14,leading=16)flowables = [Paragraph(arabic_text, normal_arabic)]doc.build(flowables)
这将生成如下图所示的文档：
英文:
Reportlab has partial bidirectional support using Fribidi. It is disabled by default. There is an option rtlSupport in reportlab/rl_settings. See user guide section on site configuration. In my installation, I added a file ~/.reportlab_settings and added the line rtlSupport=1.
In ParagraphStyle() set wordWrap="RTL".
An example:
from reportlab.platypus import Paragraphfrom reportlab.lib.enums import TA_RIGHTfrom reportlab.pdfbase import pdfmetricsfrom reportlab.pdfbase.ttfonts import TTFontfrom reportlab.lib.pagesizes import LETTERfrom reportlab.lib.styles import ParagraphStyle, getSampleStyleSheetfrom reportlab.platypus.doctemplate import SimpleDocTemplatepdfmetrics.registerFont(TTFont("Arial Unicode", "Arial Unicode.ttf"))arabic_text='وحدة1 وحدة2'doc = SimpleDocTemplate("repro_ar.pdf",pagesize=LETTER,rightMargin=280,leftMargin=280,topMargin=72,bottomMargin=72,)styles = getSampleStyleSheet()normal_arabic = ParagraphStyle(parent=styles["Normal"],name="NormalArabic",wordWrap="RTL",alignment=TA_RIGHT,fontName="Arial Unicode",fontSize=14,leading=16)flowables = [Paragraph(arabic_text, normal_arabic)]doc.build(flowables)
